Some projects are collecting money from ICOs [selling some tokens] "I do not recommend it."
You can rely on donations as an initial stage and when the project is successful you will find a lot of attention and support. "Your idea must make a real transition."

Start with self-financing and design the whitepaper and then exploit this forum and some sites for publicity and get investors "the best way but require patience." If the project is as small as "BitcoinTalk Public Information Project (BPIP)," you can find some here ---> Project Development.
